We had a really nice stay at Chanya's apartment. It was well situated, the next BTS station is just a 5 minutes walk away. Restaurants and shops like 7/11 are nearby.
The appartement was very clean and the AC did work well. Please note the mattress feeling very hard (for our European backs), also keep in mind that there is no towel provided. the apartment is kept functional. It works fine for a short stay, if you want something that is nicer than a hostel for example. Communications with Chanya was very easy and quickly answered. However the staff members didn't speak English, which was no big deal since everyone was very nice and patient.
A stay at Chanya's apartment is well recommended for anyone travelling on a budget.
